Subgenus Heizmannia was found to be monophyletic in the phylogenetic studies of Reinert et al. (2004, 2009), in a derived relationship relative to the paraphyletic subgenus Mattinglyia.

Bionomics and disease relations:

The immature stages of species of subgenus Heizmannia are found primarily in tree holes and split, cut and bored bamboo, but also occur in other types of container habitats and sometimes in ground water and crab holes. Adults of most species are known to readily attack and bite humans in shaded forest habitats.

As far as known, species of subgenus Heizmannia are not of medical importance to humans.

Distribution:

Species of the subgenus are distributed mainly in the Oriental Region, with a few species recorded from southeastern areas of the Palaearctic Region (Chin, Japan, South Korea). Heizmannia aurea is only species known from the Australasian Region (Halmahera, largest island of the Maluku Islands [Moluccas], Indonesia.
